The multiple defined errors is due to the code not being GCC 10 compliant, since it defaults to -fno-common now.

doragasu commented on 2020-06-24 18:35

That error can be solved by changing the comparison in mw_putc function to this:

static void mw_putc(megawifi *mw, uint8_t v)
    if (mw->receive_bytes >= sizeof(mw->receive_buffer)) {
    mw->receive_buffer[mw->receive_bytes++] = v;

But it still fails to build, with a lot symbols multiply defined.

Fails to build for me :(

Blastem segfaults if it can't find the images/ directory. This seems to be new to 0.6.2. The offending line of code is in nuklear_ui/blastem_nuklear.c 1382. With no images to load, controller_image is nothing so a division by zero occurs.

AFAIK, the optional dependencies are only required for the menu.bin ROM. I do not get any segfaults when entering the controllers menu. But I have no gamepads plugged to my computer, so the menu only has the "Back" button.

I get a segfault when selecting the "controllers" menu option. The program author thinks it may be a packaging issue. For more, see

Also, I'm confused about the vasm and xcftools optional dependencies. Are they only for generating the menu.bin ROM, or are they also needed for the Nuklear UI?

Stable version 0.6.2 is out!

Version 0.6.1-1 fails to pass the validity check.

darkfm commented on 2017-08-02 02:05

It should work now. I set permissions to the "games" group so if you're not already part of it, you should add yourself.

Plus, it doesn't run out-of-the-box due to permission errors (crashes when trying to run a binary):

Giving +x to the shaders directory fixed it for me.
